A 2.2-pJ/bit 10-Gb/s forwarded-clock serial-link transceiver for IoE applications

This paper presents a 10-Gb/s power-efficient serial-link transceiver for the Internet-of-Everything applications. The proposed transceiver employs several techniques to reduce the power consumption. This includes the use of forward clocking with a simplified clock recovery scheme, multiplexing the transmitted signal at the output of voltage-mode drivers, and using modified slicers in the receiver side. The proposed transceiver is implemented using a 130-nm CMOS technology. It can transmit and receive 10-Gb/s serial data while employing a 5-GHz forwarded clock. The transceiver consumes 17.5 mA from a 1.2-V supply achieving a power efficiency of 2.2 pJ/bit.
